changelog

The PCI Utilities package contains a library for portable access to PCI bus configuration registers

	* lspci.man, setpci.man: Improved the man pages. Documented all access
	methods and which operations are privileged.

	* lspci.c: Another rewrite of config register caching, now also including
	lots of internal checks. It should be now perfectly able to cope with
	portions of the configuration space being inaccessible, for example
	due to insufficient access rights.

	* lspci.c (show_pcix_nobridge, show_pcix_bridge): Cleaned up dumping of PCI-X
	capabilities. Includes partial support for PCI-X 2.0 (probably incomplete
	as I haven't seen the spec).

	* lspci.c: Quell warnings about unused parameters.

	* lspci.c: Removed C++ comments.

	* lib/header.h: Merged definitions of extended capabilities and some new
	PCI-X capability bits from linux-2.6.11/include/pci.h.

	* lspci.c (show_caps): Try to scan extended capabilities only if the
	device has either PCI-X or PCI Express capability in its normal capability
	list.

	* lib/dump.c (dump_init): Reading of dumps works again. The dump reader
	now also remembers how much data it has read and refuses attempts to
	access more than that.

	* setpci.man, lspci.c, README: prefer spelling "buses" over "busses".

	* lspci.c: If alloca() is not available, use xmalloc(), not malloc().

	* lib/configure: Added x86_64 on Linux.

2005-08-22  Martin Mares  <[e-mail]>

	* lib/filter.c (pci_filter_parse_slot): Fixed parsing of domain filters.
	Thanks to Matthew Wilcox for bug report.

	* lspci.c: Corrected spelling of "Hz" (it was "hz" at several places).
	Thanks to Krzysztof Oledzki for pointing that out.

2004-08-19  Martin Mares  <[e-mail]>

	* pciutils.spec (%attr): Setting attributes for /sbin/* is an anachronism,
	because pciutils by default install to /usr/sbin. Update.

2004-08-13  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test8.

	* lib/types.h, lib/pci.h, lib/sysdep.h: `byte' and `word' are
	no longer exported to the outside world.

	* README.Windows: Updated.

	* maint/release: Substitute version number in win32/config.h.

	* win32/config.h: Added.

	* lib/sysdep.h (bzero, strcasecmp): are macros on Windows.

	* compat/getopt.[ch]: Added copies of getopt.[ch] from the GNU
	C library for use on systems where the default libraries lack
	proper getopt. Currently used by the Windows port.

	* lib/sysdep.h, lib/types.h: Updates of the Windows port from
	Alexander Stock.

	* lib/types.h: If PCI_HAVE_Uxx_TYPES is defined, libpci doesn't define
	its own u8, u16, u32, byte and word types and uses what the user
	has supplied instead. With this change, all namespace clashes should
	be gone.

	* Makefile, lib/Makefile: Updated dependencies.

	* pciutils.h: Include lib/sysdep.h and move NONRET et al. there.

	* lib/sysdep.h: No need to include <sys/types.h> on FreeBSD, because
	it is included unconditionally in lib/types.h.

	* Moved system-dependent stuff from lib/internal.h to lib/sysdep.h,
	which is also used by the utilities. Also moved type declarations
	from lib/pci.h to lib/types.h.

	* All files: Prepend a "PCI_" prefix in front of all configuration
	defines to avoid namespace clashes. CAVEAT: If there is any libpci
	application using the (undocumented) defines, it has to be updated.

	* lib/Makefile: Killed HAVE_OWN_HEADER_H, since we stopped sharing
	headers with the kernel a couple of years ago.

	* lib/sysfs.c (sysfs_get_resources): We have 7 resources, not 6.

	* lspci.c (show_rom): Use the same logic for printing disabled
	or unassigned ROM's as we do in show_bases() for the other BAR's.

	* lib/generic.c (pci_generic_fill_info): Better reaction to
	invalid 64-bit addresses. Also d->hdrtype should not include
	bit 7, which caused mysterious errors on multi-function devices.

	* lib/generic.c (pci_generic_fill_info): Fill in base addresses
	even if the regions are known to be disabled. It is the client's
	job to interpret them. (And it is not a trivial job if you want
	to do it correctly, since you need to check I/O and memory enables
	on all upstream bridges, too.) However, it could be interesting to
	introduce functions for interpreting the addresses and even for
	mapping the regions and doing I/O on them.

2004-07-30  Martin Mares  <[e-mail]>

	* lspci.c: HyperTransport improvements from Maciej.

2004-07-11  Martin Mares  <[e-mail]>

	* lib/sysfs.c (sysfs_get_resources): Arguments now correspond
	to the format string. [Patch by Bill Nottingham]

2004-07-05  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test7.

	* lspci.c (config_fetch): Wanted to merge Matthew's bug fix, but
	ended up with rewriting the fetching mechanism to be fully dynamic,
	but avoid reading config space registers not explicitly requested.

2004-06-29  Matthew Wilcox <[e-mail]>

	* lspci.c: More work on PCI Express dumping.

	* lib/header.h: Updated PCI Express capability definitions.

	* lib/proc.c (proc_read): Removed bogus warning.

	* common.c (xrealloc): Introduced.

	* lspci.man: Added -xxxx.

2004-06-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test6.

	* lspci.c (show_msix), lib/header.h: Added dumping of MSI-X cap.
	Patch by Roland Dreier <[e-mail]>, cleaned up by me.

	* lspci.c (show_pcix_nobridge, show_pcix_bridge): Handle config_fetch()
	failures.

	* lib/header.h: Added PCI Express extended capabilities. Again by Matthew.

	* lspci.c (show_express): Added dumping of PCI Express cap.
	Patch by Matthew Wilcox.

	* lib/header.h: Added a list of PCI 3.0 capabilities and also details
	on PCI Express caps. Patch by Matthew Wilcox <[e-mail]>.

	* lspci.c (check_root): Gone. No explicit checks for root are needed,
	report correct errors reported by the libpci instead.

	* lspci.c: Added dumping of the extended config space on "-xxxx".
	Better caching of config registers.

	* setpci.c (main): Allow access to whole 4096 bytes of the config space.

	* lib/sysfs.c, lib/proc.c: Don't print error messages on short reads,
	just return the appropriate error code.

	* lib: Added support for extended (4096-byte) configuration space,
	currently implemented only in Linux proc and sysfs access methods
	and of course in the dump reader.

2004-05-29  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test5.

	* lib/pci.h: Windows don't have the standard u_int* types.

	* lib/internal.h: <sys/param.h> required on Windows for endianity
	macros.

	* lib/i386-ports.c: Connected i386-io-windows.h.

	* lspci.c (check_root): geteuid() is not available on Windows.

	* lib/i386-io-windows.h: Added Windows port contributed by Alexander
	Stock <[e-mail]>.

	* lib/configure: Hopefully fixed SunOS port broken by various
	changes to the configure script.

	* Makefile, lib/configure: Cross-compilation support, patch by Maciej.

2004-05-28  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test4.

	* lspci.c (show_verbose): Header type 1 is probably legal for all
	types of bridges, not only for PCI-to-PCI bridges.

	* lspci.c (format_agp_rate): Write "x16", not "x@".
	(show_agp): rate[] could overflow.
	Bugs reported by Jakub Bogusz <[e-mail]>.

	* lspci.c (show_ht_*): Show HyperTransport capability with all its
	details. Once again code by Maciej simplified (i.e., possibly broken)
	by me.

	* lib/header.h: Added declarations of HyperTransport capability.
	Again thanks to Maciej.

	* lspci.c: Decode all bits of the secondary status word in type 1 headers.
	Thanks to Maciej W. Rozycki <[e-mail]> for the patch.

2003-12-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test3.

	* lspci.man, setpci.man: Document domains and correct spelling.

	* lib/dump.c (dump_init): Added ability to read domain numbers.

	* lspci.c: Devices in domains different from 0 have their slot number
	printed as "<domain>:<bus>:<slot>.<func>". Tree view supports domains
	as well.

	* lib/filter.c: Slot filters understand domains.

	* lib/generic.c: Mention the domain in slot numbers in all error messages.

	* lib/internal.h: The #ifdef for Linux <asm/byteorder.h> was wrong.

	* lib/access.c (pci_get_dev): Added support for domains.

	* lib/sysfs.c (sysfs_scan): Read vendor and device ID from the config
	registers (or to be precise, leave it for the generic parts of the pcilib
	to do so) instead of reading them from the sysfs. It's faster this way.

	* lspci.c (show_pcix): Don't touch pci_dev->hdrtype, it's an internal
	variable. Better read it from the config registers (it's cached anyway).

	* lib/sysfs.c (sysfs_scan), lib/proc.c (proc_scan): Don't read the hdrtype.
	  lib/generic.c (pci_generic_fill_info): If hdrtype is -1 (unset), read it.
	  Saves lots of unnecessary file accesses.

	* lib/pci.h (PCIADDR_PORT_FMT): Use %llx instead of %Lx, because the latter
	is not supported by all C libraries.

	* Makefile: Always enter the lib directory (remember that we don't have
	full dependecies for the library in the top-level Makefile; hmmm, another
	thing to rewrite some day).

	* lib/sysfs.c: Added Linux sysfs access method based on the patch
	written by Matthew Wilcox <[e-mail]>.

	* lib/proc.c: Renamed the access method name from "/proc/bus/pci" to "Linux-proc".

	* lib/pread.h: The hacks to support pread on various versions
	of Linux libc moved there.

	* lib/proc.c (proc_setup): The return value of snprintf() varies
	between glibc versions, so we need to check both for a negative
	values and for too large values.

	* Removed last few references to the "Linux PCI Utilities", the
	package is pretty cross-platform now :)

2003-12-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test2.

	* README, pciutils.lsm, pciutils.spec: Use @VERSION@ to make the
	release scripts insert the current version. "make release" is gone.

	* maint/release, maint/release.pm: Added a new system of scripts for
	making releases including inter-version diffs etc.

	* Makefile: Cleaned up.

	* lib/fbsd-device.c: I patched another copy of this file by mistake,
	this time the version checks should be right.

2003-12-27  Martin Mares  <[e-mail]>

	* Released as 2.1.99-test1.

	* pciutils.h, common.c, lspci.man, setpci.man, lib/internal.h:
	Remove shadows of the syscall access method which was never
	implemented.

	* update-pciids.sh: Try to preserve permissions of the old file
	if chmod supports --reference. Should close Debian Bug #223740.

	* lib/proc.c (proc_setup): Increased path name length limit to 1024.
	Thanks for Redhat and Mandrake for inspiration.

	* lib/configure: Recognize ppc and ppc64, both have 64-bit addresses.
	Grabbed from Redhat (Fedora) patches.

2003-12-27  Martin Mares  <[e-mail]>

	Merged bug fixes from Debian patches:

	* lspci.c (show_verbose): "Cache Line Size" should be capitalized.

	* lspci.c (show_pcix_nobridge): Added a missing newline.

	* lib/proc.c (proc_scan): When reading the header type, don't
	forget to clear the topmost bit indicating that the device has
	multiple functions.

2003-12-27  Martin Mares  <[e-mail]>

	Updated the FreeBSD port. Thanks to Samy Al Bahra <[e-mail]>
	for the patches:

	* lib/Makefile: Add ${FREEBSD_SYS} to the include path if it's defined.
	* lib/fbsd-device.c: Select the right set of system includes according
	to __FreeBSD_version.

2003-12-27  Martin Mares  <[e-mail]>

	Merged support for Solaris on i386 by Bill Moore <[e-mail]>
	and cleaned up:

	* lib/configure: Recognize SunOS.
	* lib/internal.h: Learn how to recognize byte order on SunOS.
	* lib/i386-ports.c: Split OS-dependent I/O port access from i386-ports.c.
	* lib/i386-io-linux.h: Linux specific part.
	* lib/i386-io-hurd.h: GNU/Hurd specific part.
	* lib/i386-io-sunos.h: SunOS specific part.

2003-12-26  Martin Mares  <[e-mail]>

	* lib/header.h (PCI_*_MASK): Cast to pciaddr_t explicitly.

	* lib/pci.h: Types declared in <sys/types.h> should be usable on all
	platforms we currently support, so kill the forest of #ifdef's and
	use them in all cases.

	* lib/pci.h: Use ULONG_MASK to decide whether we should use long
	or long long to represent a 64-bit address. Killed HAVE_LONG_ADDRESS.
	Define format strings for addresses, port numbers and IRQ numbers
	directly in pci.h.

	* lib/proc.c (proc_scan): Use PCIADDR_T_FMT for scanf'ing addresses.

2003-12-26  Marco Gerards  <[e-mail]>

	Added support for the GNU Hurd (cleaned up by Martin Mares):

	* lib/configure [GNU]: Use the i386 ports for configuration access.
	* lib/i386-ports.c: Don't call iopl() on the Hurd.
	* lib/pci.h [OS_GNU]: Include <sys/types.h> and use it for defining
	u8 to u32.

2003-12-26  Martin Mares  <[e-mail]>

	* lspci.c (show_pcix_bridge, show_pcix_nobridge): Don't forget to call
	config_fetch() to ensure that the registers have been read. Thanks to
	Bill Wood <[e-mail]> for the patch.

	* lspci.c: Ensure that failure of config_fetch() is handled correctly
	at all places.

	* lspci.man: There was one more explicit reference to /usr/share/pci.ids.
	Changed to @SHAREDIR@. Patch from Maciej W. Rozycki <[e-mail]>.

	* setpci.c (main): Better error messages.

	* setpci.c (ex_op): The demo mode should disable only writing, not reading.

	* setpci.man: The documentation was inconsistent on what should -D do.
	Document the new behaviour.

	* pciutils.h, common.c, setpci.c: Introduced a NONRET macro encapsulating
	the GCC specific __attribute__((noreturn)) and killed the hack with
	redefining __attribute__ on non-GCC compilers.

	* Makefile: Added missing dependencies. Parallel builds work now.
	Problem reported by Andreas Haumer <[e-mail]>, but I chose
	a different fix.

	* Makefile (MANDIR): Use `:=' instead of `=' to avoid executing the shell
	command every time $(MANDIR) is referenced.

	* lspci.c (main): The error message for `lspci -s' incorrectly mentioned
	a `-f' switch. Reported by Steve Finney <[e-mail]>.

	* lib/generic.c: Removed memory leak in pci_generic_bus_scan().
	Reported by Gary Parnes <[e-mail]>.

	* Replaced obsolete syntax of __attribute__((unused)) in the middle of
	parameter declarations (which is no longer supported by GCC 3.1) by the
	current syntax (attribute at the end). Thanks to [e-mail]
	for reporting this problem.
